@RattiDave: Decorative screws are unnecessary, as are longer decorative screws for that matter. Modern glue like TiteBond, when cured 24 hours is stronger than the wood fiber it is bonding, and those are hardly dabs. The only reason the pin nailer is used at all is to hold the pieces in place without clamps until the glue drys and expedite assembly. There are several time saving tips that could be applied to the cutting out of pieces but that’s about the only suggestion I would make. This is a rather crude method and not much attention is paid to squareness of the components but is entertaining. Amateur attempting this as demonstrated would probably not see the same results and a lot of measuring and checking for squareness was done off camera I’m sure to make the finished chest even as nice as it looks. Entertaining and fun to watch and good enough instruction for a first starter project. But no, the dimensions of the wood, the copious amounts of glue and the lap joinery make that chest a sole survivor do an EF5 tornado, lol.
